Tecreddy RV City Water Inlet Black — Fresh Water Fill Flange with Brass Check Valve, 3/4 GHT / 1/2 NPT, UV‑Resistant

Tecreddy RV City Water Inlet is a durable fresh-water fill flange with a brass check valve that provides a leak-resistant, one-way connection for camper and trailer water hookups.

This replacement inlet is built to simplify filling and protecting your RV’s potable water system. It pairs a 3/4" GHT-compatible internal thread with a 1/2" NPT external thread and a 3-inch flange diameter to fit most RVs, campers, and trailers. High-quality brass internals and UV-resistant plastic housing reduce corrosion and wear from road use, salt, and sun exposure. The easy-grip knob and straightforward installation mean you can swap an old inlet quickly without special tools.

How does this inlet prevent backflow into my fresh water tank?

The Tecreddy inlet includes an internal brass check valve that allows water to flow into the RV but stops reverse flow, lowering contamination risk. The valve is factory-sealed to maintain one-way operation and is compatible with standard city water pressure when hooked up correctly.

• Built-in brass check valve ensures one-way flow
• Prevents siphoning and back-contamination
• Works with typical city water pressures without modification

Will this fit my RV or camper plumbing?

This inlet is designed for broad compatibility: the internal 3/4" GHT thread connects to standard garden hoses and city water sources, while the external 1/2" NPT thread fits common RV plumbing adapters. The 3-inch flange diameter gives a secure cosmetic fit for many exterior cutouts.

• 3/4" GHT internal thread for garden hoses/city hookups
• 1/2" NPT external thread for plumbing connections
• 3-inch flange diameter to match typical RV openings

How easy is installation and maintenance?

Installation is straightforward: remove the existing inlet, align the flange, and thread the new unit into place. The large grip knob speeds hose attachment and detachment without tools, and the brass components minimize routine maintenance and corrosion issues.

• Tool-free hose connection with easy-grip knob
• Replace existing inlet in minutes with basic hand tools
• Brass thread and durable housing reduce upkeep

What materials and durability features does it offer?

The Tecreddy inlet combines brass internal components with a rugged plastic exterior designed to resist UV, salt, and impact. Those materials extend service life and keep seals tight under road vibration and temperature changes.

• Brass check valve and threaded pipe for corrosion resistance
• UV-resistant plastic housing that resists cracking and fading
• Robust construction tolerates outdoor exposure and road wear
